Lachlan Morton from EF Cycling is riding from Munich to the Ukraine border in an attempt to raise money for Global Givings Ukraine Relief Fund.
ETA: Lachlan's team's sponsors have agreed to double match his stated fundraising goal of $50,000. So they'll donate $100K and he's already surpassed his goal.
Lachlan has almost completed his ride (slightly over 38 hours in) and raised over $190K (not counting sponsor matching funds). Lots of people came out during his ride to ride with him part of the way or just show support and encouragement.
